QuickField supports multiphysics analysis: different field problems are simulated together, with the result of one analysis used as input data for another. The second (“target”) problem must be built on the same geometric model as the “source” problem, and can incorporate the already-computed field values or some derived parameter distribution, while also allowing the other loads and boundary conditions typically used in that type of field analysis.
Multiple coupling types can be combined within a single problem. For example: current distribution, electrostatic field and magnetic field can each be computed on the same model file, Joule heat can then be used to compute the temperature distribution, and finally the stress produced jointly by temperature, electromagnetic force and electric force can be computed.
QuickField's multiphysics coupling currently supports the following specific data-transfer types between 2D source and target problems.
Rows are the “source problem”, columns are the “target problem”; each cell shows the data that can be transferred.
